“…The idea of a position-dependent visualization has been widely developed since the first immersive virtual reality and CAVE environments [2,3,5,4,7,6,1]. With this paper we are introducing an approach that differs from the literature since it adopts a novel and robust head tracking system that is based on a simple modification of standard LCD shutter glasses.…”

In many visual interaction applications the user needs to explore a scene by moving with respect to the virtual environment. Using a fixed camera viewpoint leads to visual inconsistencies, which can be avoided only if the exact pose of the user head is known and can be used to produce a perspective correct rendering. To this end, tracking devices are often used, however many of them are relatively expensive or require the user to wear special apparel. With this paper we present a tracking system that can be implemented with a simple and very low cost modification of standard shutter glasses. The accuracy of such approach has been evaluated quantitatively with a specially crafted experimental setup.

“…Kevin [4] discussed characteristics of head-coupled stereo display; he also dealt with the issues involved in implementing headcoupled perspective correctly. Buchanan [5] proposed a viewdependent rendering set-up for home computer use. Paul Baker [6] introduced a correct method to stereoscopic rendering with an off-axis setting for two offset cameras.…”

In this research, we suggest and implement a virtual reality system which dynamically generates the 3D stereoscopic content based on the viewing direction of the user towards a 3D screen. We propose a new approach for computing projection parameters used in OpenGL. The well-known stereoscopic rendering technique, which is called off-axis, is replaced by proposed technique that involves the changes of camera position into the process of constructing two viewing frustums for typical 3D rendering. We also introduce an approach to estimate viewer's face position in the physical screen space using inverse intrinsic matrix of digital webcam known through calibration process. Then, we extract and assign the eyes positions to virtual stereo camera positions in rendering pipeline. With the system, the real 3D perspective is achieved by using only inexpensive devices, and rendered content remains as a real physical scene with immersive dimension.

“…Stereo vision is exploited, for instance, by Hoang et al [6], that used standard head tracking techniques to allow slight head movements when looking at a 3D scene on a monitor. The concept is very similar to the non-stereoscopic technique proposed a few years earlier by Buchanan and Green [7]. In those cases, while the correct projection is always offered to the user, he is not allowed to inspect the object by moving around it.…”

Traditional stereoscopic displays assume the viewer to be standing at a specific location, that is the same pose (relative to the screen) of the stereo camera pair that depicted the scene (physically or virtually). Even for basic applications, such as movies or games, this leads to visual inconsistencies as soon as the user moves his head. Moreover, with this premises, it is not possible at all to develop more sophisticated 3D applications, involving the freedom for the user to walk around objects or to interact with them. The most popular solution to these limitation is to track the user head in order to produce a scene rendering that can be seen correctly from his point of view. With this paper we propose a viewer-dependent system that is very easy to implement since it is based on a simple augmentation of basic shutter glasses used in standard stereoscopic setups. Furthermore, we introduce a practical and sound method to quantitatively assess the accuracy of any view-dependent display approach. This fills a clear shortcoming of the currently adopted evaluation methods, that are for the most part qualitative
